Puzzle Retreat allows players to take as much time on an individual puzzle as they’d like, reset it as many times as they want and even skip the puzzle entirely.

Additional skill requirements are often added in for variety, for example a puzzle sequence in a first person shooter or a button mashing round in a quiz game. These can add interest, but also exclude unnecessarily. A good solution is to make these challenges that sit outside the core mechanic optional, either through a contextual skip option, settings, or as part of a difficulty level choice.
